Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Vorrichtung und ein Verfahren insbesondere zur Verbesserung einer Regeneration von Abgasnachbehandlungsvorrichtungen, wie insbesondere nach dem Oberbegriff von Anspruch 1 und von Anspruch 9.The invention relates to a device and a method, in particular for improving a regeneration of exhaust aftertreatment devices, in particular according to the preamble of claim 1 and of claim 9.

Stand der TechnikState of the art

Bei modernen Fahrzeugen wird der Antriebsmotor, wie beispielsweise die Brennkraftmaschine, mittels einer elektronischen Steuereinheit elektronisch gesteuert und/oder geregelt. Diese Steuerung und/oder Regelung hat Einfluss beispielsweise auf die Leistung, die Drehzahl, das Drehmoment des Antriebsmotors, aber auch auf das Abgas, wie die Abgasmenge, dessen Zusammensetzung und der Abgastemperatur.In modern vehicles, the drive motor, such as the internal combustion engine, is electronically controlled and / or regulated by means of an electronic control unit. This control and / or regulation has influence, for example, on the power, the speed, the torque of the drive motor, but also on the exhaust gas, such as the amount of exhaust gas, its composition and the exhaust gas temperature.

Bei manchen Anwendungsfällen, wie beispielsweise bei Fahrzeugen, ist in dem Abgasstrang der Brennkraftmaschine ein Partikelfilter vorgesehen, in welchem die von der Brennkraftmaschine emittierten Partikel eingelagert werden. Die Partikel können dabei brennbar sein, wobei sie auf Kohlenstoffbasis basieren können und durchaus als Rußpartikel bestehen können. Die heute verwendeten Partikelfilter haben nur eine endliche Aufnahmekapazität und müssen nach einer vorbestimmten Betriebsdauer immer einmal wieder regeneriert werden. Dies geschieht, indem die eingelagerten Partikel oxidiert werden, wobei bei diesem Oxidationsprozess Wärme freigesetzt wird. Diese Freisetzung von Wärme muss kontrolliert werden, da ansonsten bei einer unkontrollierten Oxidation Temperaturen oder Temperaturspitzen im Partikelfilter erreicht werden können, die den Partikelfilter hinsichtlich seiner Funktion und/oder Haltbarkeit schädigen oder gar zerstören können. Derzeit wird gemäß Stand der Technik die Eingangstemperatur des Abgases, das in den Partikelfilter gelangt, soweit angehoben, bis eine Schwellentemperatur für die Oxidation der Partikel erreicht oder überschritten ist.In some applications, such as in vehicles, a particulate filter is provided in the exhaust line of the internal combustion engine, in which the particles emitted by the internal combustion engine particles are stored. The particles can be combustible, whereby they can be based on carbon and can certainly exist as soot particles. The particle filters used today have only a finite capacity and must be regenerated again after a predetermined period of operation. This is done by oxidizing the embedded particles, whereby in this oxidation process Heat is released. This release of heat must be controlled, otherwise temperatures or temperature peaks in the particle filter can be achieved in an uncontrolled oxidation, which can damage the particle filter in terms of its function and / or durability or even destroy. At present, according to the prior art, the inlet temperature of the exhaust gas entering the particle filter is raised until a threshold temperature for the oxidation of the particles has been reached or exceeded.

Dabei wird nach dem Stand der Technik eine Regeneration eines Partikelfilters durchgeführt, wenn vorgegebene Bedingungen, wie der Temperatur des Abgases o.ä., erreicht sind, wobei bewertet wird, ob es notwendig und günstig ist, eine Regeneration einzuleiten.In this case, according to the prior art, a regeneration of a particulate filter is performed when predetermined conditions, such as the temperature of the exhaust gas or the like, are reached, it being evaluated whether it is necessary and favorable to initiate a regeneration.

Dabei kann es durchaus kritisch sein, wenn es notwendig wäre, eine Regeneration einzuleiten, aber die dafür günstigen Bedingungen nicht vorliegen, so dass beispielsweise mangels Last und/oder Volumenstrom des Abgases keine Regenerationsbedingungen erreicht sind. In einem solchen Falle würde die Einleitung der Regeneration nicht den gewünschten Erfolg bringen, weil die für die Regeneration notwendigen Temperaturen nicht erreicht werden könnten. In einem solchen Fall würde das Motorsteuergerät auf einer Anzeige des Fahrers im Cockpit eine Anzeige generieren, wonach eine Werkstatt auszusuchen wäre oder es wird alternativ ein so genannter "Speed-Request", also eine Anfrage für eine höhere Fahrgeschwindigkeit, angezeigt. Diese Anfrage für eine höhere Geschwindigkeit soll dem Fahrer des Fahrzeuges signalisieren, dass eine Regeneration des Partikelfilters durchgeführt werden soll und dass es dazu günstig sei, wenn eine höhere Fahrgeschwindigkeit erreicht wird, weil dadurch die benötigte Abgastemperatur erreicht wird.It may well be critical if it would be necessary to initiate a regeneration, but the favorable conditions are not present, so that, for example, no regeneration conditions are reached due to lack of load and / or volume flow of the exhaust gas. In such a case, the initiation of the regeneration would not bring the desired success, because the temperatures necessary for the regeneration could not be achieved. In such a case, the engine control unit would generate a display on a display of the driver in the cockpit, after which a workshop would be selected or alternatively a so-called "speed request", ie a request for a higher driving speed, is displayed. This request for a higher speed is to signal to the driver of the vehicle that a regeneration of the particulate filter should be carried out and that it would be favorable if a higher driving speed is achieved, because thereby the required exhaust gas temperature is reached.

Diese Art von Anzeigen sind jedoch für den Fahrer des Fahrzeuges eher ungewohnt und können ihm signalisieren, dass mit dem Fahrzeug etwas nicht in Ordnung ist, was dem Fahrer grundsätzlich unangenehm ist und somit eher nicht erwünscht ist, weil der Fahrer durch die Anzeige eines Werkstattaufenthaltes entweder mit einem Zeitverlust durch das Aufsuchen der Werkstatt rechnet oder die Information auf der Anzeige nicht versteht und die Anzeige als Fehler des Fahrzeugs fehl interpretiert.However, these types of displays are rather unfamiliar to the driver of the vehicle and can signal him that something with the vehicle is not in order, which is basically unpleasant to the driver and thus rather undesirable, because the driver expects the display of a workshop visit either with a loss of time by visiting the workshop or the information on the display does not understand and the display as a fault of Vehicle misinterpreted.

Auch Dieselrußpartikelfilter müssen regelmäßig frei gebrannt werden. Es ist ebenfalls bekannt, diese Filter in zeitlich regelmäßigen Abständen freizubrennen. Dabei kann auch hier ein Freibrennen zu einem ungünstigen Zeitpunkt erfolgen, beispielsweise kurz vor einem Fahrtende oder im ungünstigen Stadtverkehr. Ein optimales Freibrennen muss nämlich bei einer bestimmten Mindestgeschwindigkeit erfolgen und unterhalb einer Höchstgeschwindigkeit über einen definierten Zeitraum erfolgen. Wenn das Freibrennen nicht vollständig oder optimal erfolgt ist, muss bei bekannten Lösungen das Freibrennen bei der nächsten Gelegenheit erneut gestartet werden. Um das Freibrennen starten zu können, muss das Fahrzeug durch die Steuerung schnell auf Betriebstemperatur gebracht werden, was aber den Kraftstoffverbrauch erheblich ansteigen lässt.Diesel soot particulate filters must also be burnt free on a regular basis. It is also known to clear these filters at regular intervals. Here also a burn-off can take place at an unfavorable time, for example, just before a trip or in unfavorable city traffic. An optimal burn-off must namely be carried out at a certain minimum speed and carried out below a maximum speed over a defined period. If the burn-off is not complete or optimal, the burn-off must be restarted at the next opportunity in known solutions. In order to start the burn-off, the vehicle must be quickly brought to operating temperature by the controller, but this can increase the fuel consumption considerably.

Darstellung der Erfindung: Aufgabe, Lösung, VorteileDESCRIPTION OF THE INVENTION: Problem, Solution, Advantages

Es ist die Aufgabe der vorliegenden Erfindung, eine Vorrichtung und ein Verfahren zu schaffen, mittels welchem eine verbesserte Abgasnachbehandlung im Zusammenhang mit einem Dieselrußpartikelfilter erreicht wird.It is the object of the present invention to provide an apparatus and a method by means of which an improved exhaust aftertreatment is achieved in connection with a diesel particulate filter.

Erfindungsgemäß wird die Aufgabe bezüglich der Vorrichtung gelöst mit einer Vorrichtung zur Steuerung einer Abgasnachbehandlung eines Kraftfahrzeugs mit einer Diesel-Brennkraftmaschine als Antriebsmotor und einem Dieselrußpartikelfilter mit einer Steuereinheit zur Steuerung des Antriebsmotors und zum Einleiten einer Regeneration des Dieselrußpartikelfilters, wobei weiterhin eine Navigationsvorrichtung vorgesehen ist, wobei für die Steuervorrichtung und für die Navigationsvorrichtung bzw. zwischen diesen Signale oder Daten bezüglich der Steuerung der Regeneration austauschbar sind. Dabei werden Signale oder Daten ausgetauscht, um die Steuerung der Regeneration zu ermöglichen oder zu fördern, wenn die Fahrzeugbedingungen dies nicht als vorteilhaft oder möglich ansehen lassen.According to the invention the object is achieved with respect to the device with a device for controlling an exhaust gas aftertreatment of a motor vehicle with a diesel internal combustion engine as a drive motor and a diesel particulate filter with a control unit for controlling the drive motor and for initiating a regeneration of the diesel particulate filter, wherein furthermore a navigation device is provided for the control device and for the navigation device or between these signals or data relating to the control of the regeneration are interchangeable. In this case, signals or data are exchanged to allow or promote regeneration control when vehicle conditions do not suggest that this is beneficial or possible.

Ein Freibrennen kann durch eine signifikante Erhöhung der Abgastemperatur erfolgen. Diese wird dadurch erreicht, dass mehr Kraftstoff verbrannt wird, als für die eigentliche Fortbewegung notwendig wäre. Das Freibrennen kann beispielsweise 5 bis 15 Minuten, z.B. 10 Minuten, oder z.B. 5 bis 15 km, insbesondere etwa 10 km dauern.A burnout can be done by a significant increase in the exhaust gas temperature. This is achieved by burning more fuel than would be necessary for the actual locomotion. The burn-off may be, for example, 5 to 15 minutes, e.g. 10 minutes, or e.g. 5 to 15 km, in particular about 10 km last.

Der wesentliche Vorteil der Erfindung liegt also in einer Optimierung eines Zeitpunktes zum Freibrennen des Dieselrußpartikelfilters. Damit werden die Filterfunktion und die Lebensdauer des Filters optimiert. Weiterhin wird vermieden, dass ein Freibrennen kurz vor dem Erreichen des Fahrtzieles erfolgt, so dass unangenehme Geruchsbelästigungen vermieden werden.The main advantage of the invention is thus in an optimization of a time for burning the diesel particulate filter. This optimizes the filter function and filter life. Furthermore, it is avoided that a burnout is done just before reaching the destination, so that unpleasant odors are avoided.

Durch die Erfindung wird eine signifikante Kraftstoffersparnis erreicht. So ist es möglich, den Filter z.B. alle 800 km freizubrennen anstatt z.B. alle 200 km, was durch die genannten ungünstigen Bedingungen erforderlich wäre.
Dabei kann es zweckmäßig sein, wenn für die Steuereinheit ein Signal an die Navigationsvorrichtung sendbar ist, wenn eine höhere Fahrgeschwindigkeit für die Regeneration günstig oder notwendig wäre, insbesondere wenn ein so genanntes "Speed-Request"-Signal vorliegt. Auch können andere Bedingungen statt der erhöhten Fahrgeschwindigkeit angefordert werden.The invention achieves significant fuel economy. For example, it is possible to free the filter every 800 km instead of, for example, every 200 km, which would be required by the aforementioned unfavorable conditions.
It may be useful if a signal to the navigation device can be sent to the control unit, if a higher driving speed for the regeneration would be low or necessary, especially if there is a so-called "Speed Request" signal. Also, other conditions may be requested instead of the increased vehicle speed.

Auch ist es vorteilhaft, wenn für die Navigationsvorrichtung ein Signal an die Steuereinheit sendbar ist, wenn bei der berechneten Fahrtroute eine für eine Regeneration günstige Strecke vorliegt und gegebenenfalls vorteilhaft zeitnah durchfahrbar ist.It is also advantageous if a signal can be sent to the control unit for the navigation device if, in the calculated route, a there is a favorable route for a regeneration and, if appropriate, can advantageously be driven through in a timely manner.

Auch ist es vorteilhaft, wenn für die Navigationsvorrichtung ein Signal an die Steuereinheit sendbar ist, wenn eine alternative neue Fahrtroute berechenbar ist, welche eine für eine Regeneration günstige Strecke aufweist und die vorteilhaft zeitnah durchfahrbar ist.It is also advantageous if a signal can be sent to the control unit for the navigation device if an alternative new route can be calculated, which has a favorable route for regeneration and which can advantageously be driven through in a timely manner.

Gemäß eines weiteren erfindungsgemäßen Gedankens ist es vorteilhaft, wenn die neu berechenbare Strecke dem Fahrer anzeigbar und/oder zur Auswahl vorschlagbar ist.According to a further inventive idea, it is advantageous if the newly calculable route can be displayed to the driver and / or is proposed for selection.

In einer weiteren vorteilhaften Weiterbildung der erfindungsgemäßen Vorrichtung ist vorgesehen, dass jeweils ein Sensor vor und hinter dem Filter angeordnet ist, so dass ein Druckunterschied messbar ist. Der Zeitpunkt des Freibrennens kann durch die Sensoranordnung bestimmt werden, die den Druckunterschied vor und hinter dem Filter misst. Wenn diese Differenz einen bestimmten Wert überschreitet, dann wird der Freibrennvorgang gestartet.In a further advantageous embodiment of the device according to the invention it is provided that in each case a sensor is arranged in front of and behind the filter, so that a pressure difference can be measured. The time of burnout can be determined by the sensor assembly, which measures the pressure difference in front of and behind the filter. If this difference exceeds a certain value, then the burn-out process is started.

Um eine Kommunikation zwischen der Navigationsvorrichtung mit der Steuereinheit zu ermöglichen, ist es zweckmäßig, dass die Steuereinheit und die Navigationsvorrichtung mit einem Bus, insbesondere einem CAN Bus verbindbar ausgeführt sind.In order to enable communication between the navigation device and the control unit, it is expedient for the control unit and the navigation device to be connectable to a bus, in particular a CAN bus.

Die Aufgabe bezüglich des Verfahrens wird gelöst mit einem Verfahren zur Steuerung einer Abgasnachbehandlung insbesondere eines Kraftfahrzeugs mit einem Antriebsmotor, wie insbesondere Brennkraftmaschine, und einer Abgasnachbehandlungsvorrichtung, mit einer Steuereinheit zur Steuerung der Antriebsmotors und zum Einleiten einer Regeneration der Abgasnachbehandlungsvorrichtung, wobei weiterhin eine Navigationsvorrichtung vorgesehen ist, wobei die Steuervorrichtung und die Navigationsvorrichtung Signale oder Daten bezüglich der Steuerung der Regeneration der Abgasnachbehandlungsvorrichtung austauschen.The object with regard to the method is achieved with a method for controlling an exhaust gas aftertreatment in particular of a motor vehicle with a drive motor, such as in particular internal combustion engine, and an exhaust aftertreatment device, with a control unit for controlling the drive motor and for initiating a regeneration of the exhaust aftertreatment device, wherein furthermore a navigation device is provided wherein the control device and the navigation device Replace signals or data related to the regeneration control of the exhaust aftertreatment device.

Vorteilhaft ist es, wenn die Steuereinheit ein Signal an die Navigationsvorrichtung sendet, wenn eine höhere Fahrgeschwindigkeit für die Regeneration günstig oder notwendig wäre, insbesondere wenn ein so genanntes "Speed-Request"-Signal vorliegt. Auch können andere Bedingungen statt der erhöhten Fahrgeschwindigkeit angefordert werdenIt is advantageous if the control unit transmits a signal to the navigation device if a higher driving speed would be favorable or necessary for the regeneration, in particular if there is a so-called "speed request" signal. Also, other conditions may be requested instead of the increased vehicle speed

Kurze Beschreibung der ZeichnungenBrief description of the drawings

Nachstehend wird die Erfindung auf der Grundlage eines Ausführungsbeispiels anhand der Zeichnungen näher erläutert. Es zeigt:

Fig. 1
eine schematische Darstellung eines Fahrzeugs.
The invention will be explained in more detail on the basis of an embodiment with reference to the drawings. It shows:
Fig. 1
a schematic representation of a vehicle.

Bevorzugte Ausführung der ErfindungPreferred embodiment of the invention

Die Figur 1 zeigt schematisch ein Kraftfahrzeug 1 mit Antriebsmotor 2, und zwar eine Diesel-Brennkraftmaschine, bei welcher im Abgasstrang 3 eine Abgasnachbehandlungsvorrichtung , und zwar ein Dieselrußpartikelfilter 4 vorgesehen ist. Der Antriebsmotor 2 wird dabei von einer Steuereinheit 5 gesteuert, welche auf Signale und Daten des Fahrzeugs 1, des Antriebsmotors 2 und/oder der Abgasnachbehandlungsvorrichtung 4 zurückgreift.The FIG. 1 schematically shows a motor vehicle 1 with drive motor 2, namely a diesel internal combustion engine, in which in the exhaust line 3, an exhaust aftertreatment device, namely a diesel particulate filter 4 is provided. The drive motor 2 is controlled by a control unit 5, which accesses signals and data of the vehicle 1, the drive motor 2 and / or the exhaust aftertreatment device 4.

Weiterhin ist eine Ortungs- und/oder Navigationsvorrichtung 6 vorgesehen, welche aufgrund von Satelliten- und/oder Kartendaten die aktuelle Position des Fahrzeugs 1 bestimmt und beispielsweise bei fahrerseitiger Auswahl eines Zieles und einer Zielführung eine Route auswählt und den Fahrer mittels angezeigter optischer und/oder akustischer Kommandos zum gewünschten Ziel führt. Dabei greift die Ortungs- und/oder Navigationsvorrichtung 6 bevorzugt auf in einem Speicher 7 vorhandene digitale Kartendaten zu und wählt abhängig von aktuellen Standort und von weiteren vorgegebenen gegebenenfalls vorwählbaren Randbedingungen die optimale Strecke aus.Furthermore, a positioning and / or navigation device 6 is provided, which determines the current position of the vehicle 1 based on satellite and / or map data and, for example, selects a route when the driver selects a destination and a route guidance and displays the driver by means of displayed optical and / or acoustic commands to the desired destination. In this case, the positioning and / or navigation device 6 preferably accesses digital map data present in a memory 7 and selects the optimum route depending on the current location and on further predetermined optionally preselectable boundary conditions.

Die Steuereinheit 5 und die Ortungs- und/oder Navigationsvorrichtung 6 sind mit einem Bus, insbesondere einem CAN Bus verbunden.The control unit 5 and the positioning and / or navigation device 6 are connected to a bus, in particular a CAN bus.

Wie oben bereits ausgeführt, ist der Dieselrußpartikelfilter 4 derart ausgestaltet, dass dieser von Zeit zu Zeit abhängig von seiner Beladung regeneriert werden muss. Dies kann bei dem Partikelfilter 4 beispielsweise durch die gezielte Erhöhung der Abgaseingangstemperatur am Partikelfilter geschehen. Sind jedoch die aktuellen Bedingungen des Fahrzeugzustandes nicht geeignet, eine Regeneration des Partikelfilters 4 durchzuführen, weil die Abgastemperatur nicht auf die gewünschte für die Regeneration wünschenswerte Temperatur angehoben werden kann, kann ein entsprechendes Signal oder eine entsprechende Mitteilung auf der Anzeige im Fahrzeug mitgeteilt werden, wie die Nachricht, eine Werkstatt aufzusuchen oder des so genannten "Speed Requests", also eine Anfrage für eine höhere Fahrgeschwindigkeit, wonach eine Fahrtstrecke mit erhöhter Fahrzeuggeschwindigkeit bevorzugt werden würde, weil in einem solchen Fahrzustand die Abgastemperatur auf die für die Regeneration nötige Temperatur angehoben werden könnte.As already stated above, the diesel particulate filter 4 is designed such that it must be regenerated from time to time depending on its load. This can be done in the particulate filter 4, for example, by the targeted increase of the exhaust gas inlet temperature on the particulate filter. However, if the current conditions of the vehicle condition are not amenable to regeneration of the particulate filter 4 because the exhaust gas temperature can not be raised to the desired temperature desirable for regeneration, a corresponding signal or message may be communicated on the display in the vehicle, such as the message to visit a workshop or the so-called "Speed Requests", so a request for a higher speed, according to which a route with increased vehicle speed would be preferred because in such a driving condition, the exhaust gas temperature could be raised to the necessary temperature for the regeneration ,

In Falle einer Steuerung der Brennkraftmaschine 2 zur Regeneration des Dieselrußpartikelfilters 4 kann, wie bereits oben beschrieben, ein so genannter "Werkstatt-Befehl" oder ein so genannter "Speed Request"- Befehl ausgegeben werden.In the case of a control of the internal combustion engine 2 for the regeneration of the diesel particulate filter 4, as already described above, a so-called "workshop command" or a so-called "Speed Request" command can be issued.

Liegt ein solcher Befehl vor und befindet sich das Fahrzeug in einem Routenzielführungsmodus, so kann im Falle, dass der Ortungs- und/oder Navigationsvorrichtung 6 der "Speed-Request"-Befehl vorliegt, von der Navigationsvorrichtung eine Route vorgeschlagen werden, bei welcher eine erhöhte Fahrgeschwindigkeit mit höherer Wahrscheinlichkeit realisiert werden kann. So kann beispielsweise eine Autobahnstrecke oder eine Bundesstraßenstrecke vorgeschlagen werden, wenn der dadurch in Kauf zu nehmende Umweg nicht allzu groß ist und im Bereich eines voreinstellbaren akzeptablen Bereich eines Umweges liegt.If such a command is present and the vehicle is in a route guidance mode, then in the event that the location and / or navigation device 6 the "Speed Request" command is present, proposed by the navigation device, a route in which an increased Driving speed can be realized with higher probability. Thus, for example, a motorway route or a federal road route can be proposed if the detour to be taken into account is not too great and lies within the range of a presettable acceptable range of a detour.

Somit ist es vorteilhaft, wenn zwischen der Steuereinheit 5 und der Navigationsvorrichtung 6 eine Signal- oder Datenverbindung, insbesondere ein CAN-Bus, vorliegt, über welchen Signale oder Daten ausgetauscht werden können, wie beispielsweise ein "Speed-Request"-Befehl oder -Signal.Thus, it is advantageous if between the control unit 5 and the navigation device 6, a signal or data connection, in particular a CAN bus, is present, via which signals or data can be exchanged, such as a "Speed Request" command or signal ,

Im diesem Anwendungsbeispiel kann beispielsweise die Bestimmung einer neuen Route durch die Navigationsvorrichtung 6 erfolgen, gleichzeitig oder auch bevor das "Speed-Request"-Signal auf der Fahrzeuganzeige angezeigt wird, so dass in diesem Falle gegebenenfalls sogar vermieden werden könnte, das "Speed-Request"-Signal anzuzeigen, weil die vorgeschlagene Route dem Speed-Request genügt. Dies kann beispielsweise dadurch realisiert werden, dass die Navigationsvorrichtung 6 der Steuereinheit 5 ein Signal übergibt, welches dieses anzeigt. Bei der anderen vorgeschlagenen Route kann weiterhin eine Fahrerinformation ausgegeben werden, so dass der Fahrer darüber in Kenntnis gesetzt wird, dass die neue Route vorgeschlagen wird, weil diese für die Abgasnachbehandlung vorteilhaft ist. Dies dient der Akzeptanz der neuen Route beim Fahrer, wenn er die eigentlich günstigere Route kennt und dennoch eine davon abweichende Route angezeigt bekommt.In this application example, for example, the determination of a new route by the navigation device 6, simultaneously or even before the "Speed Request" signal is displayed on the vehicle display, so that in this case could possibly even be avoided, the "Speed Request Signal because the proposed route meets the speed request. This can be realized, for example, by the navigation device 6 transmitting a signal to the control unit 5, which indicates this. In the other proposed route, driver information may be further output, so that the driver is informed that the new route is being proposed because it is advantageous for the exhaust gas aftertreatment. This is the acceptance of the new route at the driver, if he knows the actually cheaper route and still gets a different route displayed.

Gemäß eines anderen Ausführungsbeispieles kann bei Vorliegen eines "Speed-Request"-Signals die Navigationsvorrichtung 6 auch abschätzen, ob in der näheren Zukunft eine Strecke zu fahren wäre, die den Anforderungen für die Regeneration des Partikelfilters entsprechen würde und somit für die Regeneration günstig wäre. Wäre dies der Fall, so könnte die Navigationsvorrichtung 6 der Steuereinheit 5 ein entsprechendes Signal senden, so dass die Anzeige des "Speed-Request"-Signals ggf. unterbleiben kann und daher nicht angesteuert wird. Entsprechend ist es vorteilhaft, wenn die Steuereinheit 5 und die Navigationsvorrichtung 6 sich Daten austauschen über das vorliegen einer Notwendigkeit einer Regeneration und der dazu vorliegenden Bedingungen. Sind die dafür vorteilhaften oder notwendigen Bedingungen vorliegend, so dass keine Information oder Anweisung an den Fahrer ausgegeben werden muss, so kann die Regeneration angesteuert und durchgeführt werden.According to another embodiment, in the presence of a "Speed Request" signal, the navigation device 6 can also estimate whether in the near future would be a route that would meet the requirements for the regeneration of the particulate filter and thus would be favorable for regeneration. If this were the case, then the navigation device 6 of the control unit 5 could send a corresponding signal, so that the display of the "Speed Request" signal may possibly be omitted and therefore not actuated. Accordingly, it is advantageous if the control unit 5 and the navigation device 6 exchange data on the presence of a need for regeneration and the conditions therefor. Are the advantageous or necessary conditions present, so that no information or Statement must be issued to the driver, the regeneration can be controlled and performed.

Weiterhin ist jeweils ein Sensor, insbesondere ein Drucksensor vor und hinter dem Filter angeordnet, so dass ein Druckunterschied messbar ist. Die gemessenen Werte könne über einen CAN Bus an die Steuereinheit 5 übergeben werden.Furthermore, in each case a sensor, in particular a pressure sensor is arranged in front of and behind the filter, so that a pressure difference can be measured. The measured values can be transferred to the control unit 5 via a CAN bus.

Nachdem also eine Route durch die Navigationsvorrichtung 6 berechnet wurde, kann in der Regel davon ausgegangen werden, dass diese Route vom Fahrzeug abgefahren wird. Anhand der Route und dem Zustand des Partikelfilters 4 kann ein optimaler Zeitpunkt zum Freibrennen des Filters 4 festgelegt werden. Dieser Zeitpunkt kann z.B. bezüglich Dauer und Geschwindigkeit optimiert werden. Dies kann anhand eines Geschwindigkeitsprofils der berechneten Route bestimmt werden. Als weiteres Kriterium könnten auch Metainformationen, wie Umweltzonen, in die Kalkulation mit einfließen. Diese Optimierung kann abgestuft erfolgen, indem bei Überschreiten eines ersten Schwellwertes der durch die Sensoranordnung erfassten Druckdifferenz versucht wird, in Zusammenarbeit mit der Navigationsvorrichtung 6 und Umgebungsparametern einen optimalen Zeitpunkt für das Freibrennen zu finden.Thus, after a route has been calculated by the navigation device 6, it can generally be assumed that this route will be traveled by the vehicle. Based on the route and the state of the particulate filter 4, an optimal time for burning the filter 4 can be set. This time may e.g. be optimized in terms of duration and speed. This can be determined from a velocity profile of the calculated route. As a further criterion, meta-information such as environmental zones could also be included in the calculation. This optimization can be carried out in a graduated manner by attempting to find an optimum time for burnout when a first threshold value of the pressure difference detected by the sensor arrangement is exceeded, in cooperation with the navigation device 6 and ambient parameters.

Bei dieser bevorzugten Ausgestaltung der Vorrichtung errechnet die Navigationsvorrichtung 6 einen optimalen Zeitpunkt für ein Freibrennen des Dieselrußpartikelfilters und legt diesen fest. Hierbei kann berücksichtigt werden, ob die Fahrt im Stadtverkehr, auf einer Landstraße oder auf einer Autobahn erfolgen wird. Beispielsweise kann die Dauer einer Autobahnfahrt berücksichtigt werden, so dass ein Freibrennen während dieser Autobahnfahrt und nicht im Stadtverkehr mit möglicher Umweltzone erfolgt. Bei der Errechnung des optimalen Zeitpunktes kann also die Dauer der in die Navigationsvorrichtung eingegebenen Fahrt und/oder die anhand der errechneten Fahrstrecke prognostizierten Geschwindigkeit berücksichtigt werden.In this preferred embodiment of the device, the navigation device 6 calculates and sets an optimal time for burnout of the diesel particulate filter. Here it can be taken into account whether the trip will take place in city traffic, on a country road or on a motorway. For example, the duration of a motorway ride can be taken into account, so that a burnout during this highway ride and not in city traffic with possible environmental zone occurs. In the calculation of the optimal time so the duration of the input into the navigation device and / or based on the Calculated driving distance predicted speed.

Die Erfindung ist nicht nur auf die beschriebenen Beispiele beschränkt. So kann anstatt eines Dieselrußpartikelfilters auch eine andere Abgasbehandlungsvorrichtung eingesetzt werden.The invention is not limited only to the examples described. Thus, instead of a diesel particulate filter, another exhaust gas treatment device can also be used.
